"blocked onebox domains" doesn't work

[RGJ (Richard - Communiteq)]

I am unable to reproduce this. Is the link in the form of https://www.youtube.com/watch?v=XXXX ? You might want to block youtu.be as well.

Also there is no one way to disable onboxes globally that I can see

Just set max_oneboxes_per_post to 0.
